I got the idea for this from the "What is faith?" thread started by @mingularity.
Time, at its most basic level, I believe reflects change. It gives things life, since if everything went static, then there would be no unfolding events to experience. But when viewed more philosophically, I can't even begin to grasp the true essence of time. Is time just an arrow extending infinitely in 1 straight direction, or is there something much more to it?
Personally, I take the latter view. It could be seen as a river of sorts, changing speed, whirling in endless spirals, branching off into alternate channels, fluctuating through different depths, ever in motion, and so forth. Perhaps it's also like an acentric labyrinth, without any clear beginning or end, going into all kinds of paradoxical configurations.
Ultimately, time may be so intricate, that even the wisest beings in existence cannot fully visualize what will happen. Maybe it's more like a web of contingencies, with all kinds of "what if" questions. I guess we need to see things in terms of questions, including time. Einstein after all says that everything relative. Time and its perceived changes must be determined by the shifting of contexts.
It may be much like swapping boxes around, each with different laws and items of various designs. Presents come in literal packages, and the metaphorical packages just described also have within them a gift, the "present" time. If we can unleash the present, then there's no telling what wonders may be wrought undreampt of in our time!
